Configuration: Don't have shared libraries depend on themselves

Configuration: Don't have shared libraries depend on themselves

The NonStop config attributes mean that there's no separate "simple"
and "full" shared library name, they are the same.  Because we assumed
that they would always differ, we ended up with this dependency:

    libcrypto.so: libcrypto.so

A simple fix was all that was needed to clear that.
